I have a RIS 2.0 Other than changes to the RCX brick, software, documentation/manuals/etc & IR tower, what parts would I need to obtain to have the equivilant of a RIS 1.5? What about a 1.0? (23 years ago, 29-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

|

Just a quick note to ask how many people are waiting on USB support for the pbForth language. I got a USB tower a couple of weeks ago and just got it working with my uploader/console last night. It uses ODD parity, so the next pbForth release will (...) (23 years ago, 27-Mar-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.pbforth)

(...) But... be aware that the 'polarity switch' has only two connectors (for two sets of wires). It's not a '3-way' where you can try to select one of two inputs by moving the lever. The action is forward-off-reverse with one power source connected (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

(...) Use a resistor to make one of the states of the switch read less than a full short. Setup as a light sensor. 0 means off 50~ means one state and 100 means another. This is the basis for alot of the touch sensor multipliers. I am sure if you (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

(...) Yes, you can use that motor with the RCX, but it draws significantly more current than the newer geared-down motors, so your batteries won't last as long. Dave (23 years ago, 24-Mar-02, to lugnet.robotics.rcx)

Basicly, what I want is a button, switch or whatever on my model that when moved one way causes one input to be sent to the RCX but when moved differently it causes a different input to be sent to the RCX. Should also have a 3rd "off" state. I am (...) (23 years ago, 24-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)
